PSU 5V 10A voltage regulation at 1A loading

Now I am coompleted the wiring of the 5A 10A PSU.  I am using an AWG18, 1.2 m power cable for the 5.1V supply.

I wanted to calculated the performance, but I forgot the voltage regulation formula which I learnt long long time ago in collage.  So I wiki to get the formula and found that the voltage regulatrion at 1A loading is about 4%.

I dared not to find the regulation at full load, because I don't which to see any white smoke coming out while testing.

Voltage regulation - Wikipedia

In electrical engineering, particularly power engineering, voltage regulation is a measure of change in the voltage magnitude between the sending and receiving end of a component, such as a transmission or distribution line.

Voltage regulation describes the ability of a system to provide near constant voltage over a wide range of load conditions.

The term may refer to a passive property that results in more or less voltage drop under various load conditions, or to the active intervention with devices for the specific purpose of adjusting voltage.


Electrical power systems

In electrical power systems it is a dimensionless quantity defined at the receiving end of a transmission line as:

Precentage VR = ((V noload - V full load) / V full load) * 100

where Vnl is voltage at no load and Vfl is voltage at full load. A smaller value of Voltage Regulation is usually beneficial.

The Voltage Regulation formula could be visualized with the following: "Consider power being delivered to a load such that the voltage at the load is the load's rated voltage VRated, if then the load disappears, the voltage at the point of the load will rise to Vnl."

Sometimes, the term voltage regulation is used to describe processes by which the quantity VR is reduced, especially concerning special circuits and devices for this purpose.
